CASTING FOR FEEDERS FOR INGOT MOLDSQ Application filed February 9, 1924. Serial It'd/691,741.

To all whom it may concern:

Be it known that BLooMrmLn H. How- ARD and ERNEST J. TURNER, citizens of the United States,- residing, respectively, at Washington, District of Columbia, and

Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Castings for Feeders for Ingot Molds, of which the following is a specification.

Our invention relates to improvements in castings for feeders for ingot molds.

. The object of our invention is to provide a casting for forming ingot mold feeders of plastic material by forcing it through a passage in a casting corresponding to the form of feeder. I I

Another object of our invention is to provide a casting in which the outer walls are bellied outwardly to conform with the shape of the feeder and having intermediate outwardly bellied walls adapted to form integral ribs for supporting the feeder on the mold and having an inner wall of a different contour whereby a perfect feeder can be formed by forcing the plastic mateparts. The inner member 21 instead of havrial under pressure between the walls of the casting.

A further object of our invention 1s to provide a specially shaped casting adapted to form a correspondingly shaped 'feeder and having certain arrangement of walls hereinafter more fully set forth.

In the accompanying drawings Figure 1 is a vertical sectional view of a cylinder showing our improved casting applied thereto, partly broken away.

Figure 2 is a horizontal transverse sectional view taken on the-line 2-2 of Figure 1.

Figure 3 is a view showing a modified form of casting.

Referring now to the drawings-1 represents the lower end of the cylinder in which the plastic material is compressed and which has anoutwardly' extending flange. 2

to which the flange 3 of the outer member,

4 of the casting is bolted by means of bolts 5. The outer member 4 of the casting is provided with four outwardly bellied walls similar to Figure 2 5, 6,7 and 8 oppositely arranged and connected at-each corner by three outwardly curved walls 9,10 and 11. The outwardly curved walls 9 and 11 form the ribs on the outer periphery of the feeder for support ing it on the upper end of the mold. The outwardly curved portion 10 conforms with the walls 5 and '8 and forms a part of the outer wall of the feeder. i c

The cylinder 1 is provided witha cylindrical member 12 centrally located and to which is bolted by means of bolt 13 the inner member 14 of the casting. This member has four outwardly bellied walls 15, 16,

17 and 18 which are arranged approxicorrespond with the beveled wall 20 of the outer member 4 and whereby the passage has an open upper end to receiv'e'the plastic material and whereby it is compressed as it enters the lower end of the passage.

In Figure 3 we have shown the outer member 4 of the casting of the same shape and like reference numerals indicate like ing'its walls bellied outwardly as shown in Figure 2 has four straight walls 22, 23, 24 and 25.

Having thus fully described our invention what we claim is: l

1. A casting for ingot mold feeders com prising anouter member having outwardly I bellied walls connected by curvedwalls arrangedin a different are of a circle, and an inner member having outwardly bellied walls corresponding with those of the outer member. i

2. A- casting for feeders for ingot molds comprising 'an outer member having out wardly bellied walls,,connected by three outwardly curved walls arranged in a difierent are of a circle and an inner member having outwardly bellied walls arranged in the same are of a circle as the outwardly bellied walls of the other member.

3. A casting for ingot molds comprising an outer member having four outwardly bellied walls connected by outwardly curved walls arranged in a different are of a circle and an inner member having four outwardly bellied walls.

4. A casting for ingot mold feeders com- 53 prlsing an outer member having four outwardly bellied walls, oppositely arranged urved walls andponneoted by outwardly o arranged in a difierent are of acircle and an inner member having four oppositely arranged straight walls;

In testimony whereof we affix our signatures.
